This technology features a Yb metal wire, which is inserted into a preform and drawn into a fiber. The Yb oxidizes and results in rare earth concentrations that cannot be achieved using conventional methods. When the Yb concentration reaches a critical level, Yb no longer radiates light, allowing for the optical pumping power to be efficiently converted to thermal energy. In a highly doped fiber, this thermal energy is then placed into a volume rod, which forms the basis for a highly efficient microheating element. This technology has an array of potential biomedical and microfluidic applications, including hand-held, portable microheaters and a micro-cauterizing tool, both critical to the field of precision surgery.
• Yb is doped into glass rather than silica, allowing for safer, more efficient light radiation
• Can be integrated into existing laser pointers.
• Hand held microheaters for medical applications among others still to be determined.
